I own two old manual only ZOOM NIKKOR lenses adapted to Fuji X, one 80-200/4 and the other 100-300/5.6. Use them for video. K & F are on the cheaper side of the filter market, so they are totally suitable for my purposes and fit the old lenses well. This is a cost effective solution. No complaints about the image quality, although the threaded ring was perhaps more robust and a little better machined, but it is still good enough.

We just love this binoculars!

This K&F Concept adapter is well made and fits my relatively heavy Zeiss zoom lens and my Fuji XT1 which provides the stabilization I was hoping for. worth the extra cost over cheaper adapters to gain that trust. Like other third-party adapters, this adapter requires manual focusing.

Solid and no games, perfect Fuji Nikkor marriage!

They are brilliant, I can see so much from this, the conclusion is excellent, really well done, would recommend to anyone.

Compact but super powerful crystal clear monocular for a serious hiker or an outdoor adventure seeker. It's always important for me to have handy binoculars or monoculars nearby to take an exceptional look at nature and our oceans and mountains. Also great for bird watching and sporting events.
K&F Concept has done it with this very affordable monocular right here. This is 10-30x40 means not only can you see the object brightly and clearly, but you can also use the zoom function. With my years of experience with binoculars and monoculars, I'd like to suggest that if you're going over anything over seven power, it's better to use a tripod. Most people blame monocular, but it's actually their hands/body movement (nothing wrong with the product) This monocular comes with excellent built-in tripod screw function. Please see all my pictures and decide for yourself.
Also, I would like to point out that the lens is 40mm with a perfect 20mm eye lens. Even when the sun goes down, you can have a wonderful view because of the larger size of the objective lens. It will take a few times to perfectly open the monocular but it is to be expected from such a wonderful product. Enjoy the sightseeing!!!
PLEASE NOTE: Tripod is not included, but it will fit any tripod. The zoom image I took is only at 10 power. It's my cell phone picture nothing fancy. Amazing right!

Great adapter for my Minolta glass on my fuji camera.

My grandson loves these binoculars.. they are very durable. I have a rough and tough grandson.
